The Slider Lite-Ball Pitching Machine from Trend Sports pitches fastballs, inside breaking balls, and outside breaking balls. The powerful A/C motor throws lite-balls at variable speeds up to 60 miles per hour. The Slider also includes an automatic ball feeder that holds 12 lite-balls. Just turn on the feeder and each ball is dropped into the Slider pitching machine every 9 seconds. Take batting practice without the need for another player. And with a simple swivel adjustment you can also hit fastballs and curve balls. Plug the Slider into any standard wall outlet or third party battery packs may be avaliable. You may also consider the optional PowerAlley or Xtender Home Batting Cages and improve your hitting right in your own backyard.
